 DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

The present invention, in some embodiments thereof, relates to the exercise and fitness industry and, more particularly, but not exclusively, to a manual weightlifting apparatus and methods of using same.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings. The invention is capable of other embodiments or of being practiced or carried out in various ways.

Generally, a manually operated weightlifting apparatus is provided which is useable by any level of user, from a professional athlete to a fitness neophyte. In some embodiments of the invention, user safety, comfort and/or exercise efficiency are enhanced over what is currently available in the art by the weightlifting apparatuses described herein. In an embodiment of the invention, a centrally located hand hold (handle), accessible from at least two sides of the apparatus, creates a comfortable distribution of weight around the hand and/or ensures there is no weight transfer and/or shifting as is common with traditional hand held weightlifting apparatuses. In an embodiment of the invention, this center mass bell configuration eliminates or at least reduces impact on wrists, hands, shoulders and/or other easily de-stabilized joins or muscle groups. While specific embodiments are described herein, it should be understood that some features and/or characteristics described with respect to one embodiment are capable of being applied to other embodiments.

In an embodiment of the invention, the spherical and/or compact design also provides for movements common to dumbbells without fear of rotating handles and/or dumbbell heads causing instability and/or limiting proper and/or safe range of motion. With a safer more effective range of motion using the center mass bell apparatuses described herein, the lifter is able to maximize not only their time under stress, but also experience more effective work under tension.
